What did the author express in Thunder?

The main purpose of this article is to criticize the bad habit of borrowing books and express great sympathy for the injured. However, there is little criticism of the borrower in the full text. On the contrary, it describes the embarrassment and misfortune of borrowers in detail, and even writes about their "bad" begging behavior and "vicious" scolding. But this kind of "bad" and "malicious" is mostly irony, and most of the "bad" is fallacy. There is a saying in China's crosstalk art that "if you are reasonable but not crooked, you won't make jokes". It is precisely because of this string of fallacies that the article is full of humor and banter.
